QEMU_ALSA_ADC_BUFFER_SIZE: integer, default = 0ДЄDC buffer size (0 to go with system default) QEMU_ALSA_ADC_PERIOD_SIZE: integer, default = 0ДЄDC period size (0 to go with system default) QEMU_ALSA_ADC_SIZE_IN_USEC: boolean, default = 0ДЄDC period/buffer size in microseconds (otherwise in frames) QEMU_ALSA_DAC_BUFFER_SIZE: integer, default = 4096ДAC buffer size (0 to go with system default)

QEMU_ALSA_DAC_PERIOD_SIZE: integer, default = 1024ДAC period size (0 to go with system default) Have you looked at the parameters you can set for Alsa? QEMU_ALSA_DAC_SIZE_IN_USEC: boolean, default = 0ДAC period/buffer size in microseconds (otherwise in frames) I never used the Alsa driver, it somehow never worked on my machine. To see the latency PA calculated, use pactl list sink-inputs, for example like so watch -n 1 'pactl list sink-inputs | grep Latency' If you want to look at PA's debug output while tinkering, kill your existing daemon with pulseaudio -k, and start a new one on a console with pulseaudio -log-level=debug (after closing ALL apps that will immediately respawn it).

VMWARE MAC AUDIO INPUT CRACKLING INSTALL

You could also install this somewhere (without changing the configure, it'll install in /usr/local) Debugging For libvirt setups, just adjust /path/to/qemu/build/x86_64-softmmu/qemu-system-x86_64ДЄnd you're good to go. On a system where you have a recent QEMU installed, the only thing left to do is use this binary in place. It will only build x86_64 and PA, to save some time :) This will create a folder x86_64-softmmu within the build folder, which contains the binary qemu-system-x86_64. configure -python=/usr/bin/python2 -target-list=x86_64-softmmu -audio-drv-list=pa On Arch, these are spice-protocol python2 ceph libiscsi glusterfs Make sure you have the packages it requires to build. From looking at the code, this should make no difference.ДЄnother thing that is really strange is that the HDA device reacts badly to upping the frequency of the QEMU audio timer.

Please make sure that the Windows device is set to a sampling rate of 44100Hz!ДЇor reasons yet unknown, HDA prefers a high buffer size, and AC97 a low one. Use these settings to get started (settings from my machine, if it does not work, maybe increase latency a bit): If you do not change any of these, it will behave like the unpatched QEMU on the output, but the input will work as expected (it does not in unpatched, there's a big delay when starting to use it from the VM) Status QuoД«oth the HDA, and the AC97 device work well. QEMU_PA_LATENCY_IN: integer, default = 10 QEMU_PA_LATENCY_OUT: integer, default = 10

VMWARE MAC AUDIO INPUT CRACKLING PATCH

The patch exposes 3 new settings: QEMU_PA_LATENCY_DYNAMIC: integer, default = 2Д®nable dynamic latency adjustment (1 - output, 2 - input, 3 - both)

The code is not ready yet, but I will finish it over the weekend. I am working on it :)ДЇuck YEA! The problem I suspected, was indeed one, and I reimplemented some stuff, and now have the HDA device crystal clear with a latency of 8ms. But I may have found a problem with the way the PA backend is implemented, which would prevent higher timer frequencies. Yea, while crackling free, the latency is too bad. I have to admit to being a noob regarding PA usage, so maybe someone's out there being able to improve this even more?

So if the crackling also itches you badly, try this and report back. On my system, this patch does the trick - I get rid of the crackling, even when not pinning the emulator to otherwise completely unused cores.Д«efore I go and submit a pull request to get this into official, I want to reach out to test this more. I decided to take a look at the code of QEMU's PA backend and found that it's latency is hardcoded at 10ms, without automatic latency adjustment, so I patched it to allow to change this via configuration. After playing around with different QEMU_PA_ environment settings, and running it against a PA daemon with debug log enabled, I found that no matter what I did, the maximum latency PA would ever reach was 4ms, nothing more.Дuring the research I found out that PA has a mode where it would adjust latency automatically depending on the actual client's behaviour. Yesterday was another one of those days when I tried to get rid of the crackling.
